Bumblebee Transistors

[macfadyb]

Hey,

First time builder of a MB board, was looking to start with the 'Bumblebee' only to find that the necessary trio of NKT213's cost around 15 a piece from what I saw!

Was wondering how much flexibility there is with substituting a different transistor, such as an AC127 or AC187?

Or would a silicon be better?

Thanks!

Welcome.

Smallbear sells a et of PNP transistors appropriate for the Buzzaround:

They aren't NKT213s, but that doesn't matter -- what does matter is that they have appropriate gain and leakage for the circuit.

You can also buy a set of Tonebender MKIII transistors. Smallbear sells those, as does Chromosphere at his store (he's in Australia, but his shipping is reasonable).

You could also buy a batch of germanium transistors from Ebay and test them, but that involves a lot of datasheet hunting to find some with the right gain ranges.

Thanks a lot man

I felt a disturbance in the Force...as if...millions of cork sniffers suddenly cried out in protest.

Exactly!  And if you sand the part number off in the name of "mojo" the price increases a lot for unobtanium components.
